For over 13 years, Dr. Jan-Peter Goldman has been researching in the field of orthopedics and biomechanics. As a scientific advisor, he is actively involved in the design of the Sizeless shoe.

What I like best is how easily the shoe adjusts as my children grow. It fits much longer than regular shoes, and we don't have to constantly buy new ones. That makes our everyday life noticeably more relaxed.
"
When my children tested the shoes, I was particularly impressed by the flexible sole and the wide toe box. I also think it's great that parents can securely fix the size adjustment, so children can't accidentally change it.

Previously, I constantly had to buy new shoes for my children. With the adjustable design, we need significantly fewer pairs, which saves money and feels much more sustainable.

Frequently Asked Questions
Why buy Sizeless?
Regular shoes have fixed sizes, but children's feet are constantly and often rapidly growing. As a result, shoes are often already too small even though they were only recently purchased.
Parents then face a choice: constantly buying new shoes or compromising on fit and comfort. Classic phrases include "You'll grow into them" or "They have to last until winter." Neither is child-friendly nor healthy. The alternative of buying multiple pairs of shoes is expensive and anything but sustainable.
We want to change that. Well-fitting shoes should be the standard, not constant repurchasing just because the foot has grown a few millimeters. Our shoe is continuously adjustable in size, flexible, and produced in Europe. That's why the size-adjustable Sizeless shoe is the better choice.
How much adjustability does the shoe have?
The shoe is adjustable up to 8 mm, which is slightly more than one additional shoe size (approx. 6.6 mm) and significantly extends the period of use. The idea is that the Sizeless shoe accompanies a child from spring to autumn, always fitting perfectly.
When will I receive my order?
Our first production in Portugal is already running at full speed, and we expect the shoes to arrive at our warehouse in Cologne by mid-July. We will then immediately begin shipping all orders to you as quickly as possible. If everything continues to go according to plan, the Sizeless shoes will arrive at your door by mid to late July 💚
Since we are still a small startup and this is our first shoe, there may still be occasional minor delays. However, we are doing our best every day to ensure that your order arrives quickly and safely with you and your little adventurers 🙂
Where are the shoes made?
Our shoes are completely produced in Portugal. We personally visited all production partners to assure ourselves of the craftsmanship, fair working conditions, and environmental standards. We were particularly impressed by the appreciative and familial atmosphere on-site.
This is how we know: Our shoes are made under good conditions with pride, care, and a smile.
How much is shipping?
Shipping is calculated based on your location and the items in your order. You will always see the shipping price before completing your purchase.
